Problem is, he already started doing it, already acknowledged the complaint filed against the accused included a charge of discharging a firearm etc. and when the media questioned him that eye witness accts don't support the suspect shooting, and that some eyewitness say the officer that was struck was hit by another officer and the accused never fired a gun...now he announces he is not talking about it.
Talk or not, fine...but don't start doing it and then when you can't answer questions about what you have openly talked about in the past, decide to stop talking. It fuels conspiracy.
